Let's Encrypt の導入

Let's Encryptには、日本語のサイトが正式には存在しない。
Let's Encrypt 総合ポータルを参考にしてみる。

Debian 9 用の Certbot パケージは Stretch backports リポジトリから取得するため、 backports リポジトリが有効にする。

$ sudo nano /etc/apt/sources.list
以下を追加
deb http://ftp.debian.org/debian stretch-backports main

$ sudo apt update

Let's Encrypt の導入

$ sudo apt -t stretch-backports install certbot
$ sudo service apache2 stop
$ sudo certbot certonly --webroot -w <ドキュメントルート> -d <ドメイン> -d <サブドメイン>

IMPORTANT NOTES:
 - Congratulations! Your certificate and chain have been saved at:
   /etc/letsencrypt/live/<ドメイン>/fullchain.pem
   Your key file has been saved at:
   /etc/letsencrypt/live/<ドメイン>/privkey.pem
   Your cert will expire on 20xx-xx-xx. To obtain a new or tweaked
   version of this certificate in the future, simply run certbot
   again. To non-interactively renew *all* of your certificates, run
   "certbot renew"
 - Your account credentials have been saved in your Certbot
   configuration directory at /etc/letsencrypt. You should make a
   secure backup of this folder now. This configuration directory will
   also contain certificates and private keys obtained by Certbot so
   making regular backups of this folder is ideal.
 - If you like Certbot, please consider supporting our work by:
